Create custom widget

Yes this is it, and how can I spawn it? I mean what is code for spawing it as graphics object and inserting into layout?

Hi

Like any c++ class.

#include "mywidget.h"

MyWidget * instance = new MyWidget();
ui->somelayout->addWidget(instance );

Thank you :)

Just as a note :)
If you really plan to use 100 instances of this, then maybe
you should use a layout inside a QScrollArea so it allows scrolling.
A layout alone. will not give scrollbars

Thanks :) Would be great if I could create folders in Forms directory :)

@mrjj Can I ask you about that scroll area?

I wanted to add widget into:

ui->scrollAreaWidgetContents

But it doesn't have a addWidget method.

Hi
Well you can.
Remove the ui/cpp/h from project. (dont check the delete file checkbox)
In the .pro file
you can add
FORMS += Controls/theForm.ui

and you can put the ui file in the sub folder Controls
and then Add the UI to the project.

You might also need to change the
INCLUDES +=Controls/theForm.h
and
SOURCES +=Controls/theForm.cpp

for it to find the .cpp and .h

Hi
Since you have ui. do the following.
Place any widget inside scroll area. (like button)
Right click besides this widget. (in scroll area)
Choose a layout in the layout menu.
Now delete this widget again. (the button)
The layout will stay!
Notice the name of the layout
then from code
ui->thenewlayoutname->addwidget(xx);

@mrjj

Yea, I have it like that:

It is scrollAreaWidgetContents, but if I do ui->scrollAreaWidgetContents->Add it shows only AddAction.

Hi
Look in the layout section of the properties.

to see the name.

And yes, its slightly confusing as the structure is a bit flatten
so
its not
ui->scrollareaSomething->layout
but just
ui->verticalLayout_5->addwidget(xxx)

@mrjj Again thank you very much!! :)
